Visual analysis for medicine
Visual analysis for medicine
Cancer, Alzheimer's, diabetes or cardiovascular diseases are what are known as non-communicable diseases, which are responsible for the majority of deaths worldwide - in Germany, an estimated 91 percent of all deaths are the result of these diseases, and it is a rising trend. Epidemiologists have been studying the development and distribution of these epidemiological diseases, as well as the measures to combat them and what their social consequences are.

AI empowers environmental regulators
AI empowers environmental regulators
Monitoring environmental compliance is a particular challenge for governments in poor countries. A new machine learning approach that uses satellite imagery to pinpoint highly polluting brick kilns in Bangladesh could provide a low-cost solution. By Rob Jordan Stanford Woods Institute for the Environment Like superheroes capable of seeing through obstacles, environmental regulators may soon wield the power of all-seeing eyes that can identify violators anywhere at any time, according to a new Stanford University-led study.

Uncovering the secrets of some of the world's first color photographs
Researchers have shed new light on one of the earliest color photography techniques, G. Lippmann's Nobel Prize-winning multispectral imaging method. It is often said that before air travel our skies were bluer yet how, in the 21 st century, could we ever know what light and colors were like one hundred years ago? Recently, a group of researchers from EPFL's Audiovisual Communications Laboratory , in the School of Computer and Communication Sciences (IC), had a unique opportunity to try to find out.

Designing better antibody drugs with artificial intelligence
Machine learning methods help to optimise the development of antibody drugs. This leads to active substances with improved properties, also with regard to tolerability in the body. Antibodies are not only produced by our immune cells to fight viruses and other pathogens in the body. For a few decades now, medicine has also been using antibodies produced by biotechnology as drugs.

Using AI to Diagnose Neurological Diseases Based on Motor Impairment
New Heidelberg approach: analysing movement patterns through machine learning The way we move says a lot about the state of our brain. While normal motor behaviour points to a healthy brain function, deviations can indicate impairments owing to neurological diseases. The observation and evaluation of movement patterns is therefore part of basic research, and is likewise one of the most important instruments for non-invasive diagnostics in clinical applications.

Topological data analysis can help predict stock-market crashes
Scientists, together with local startup L2F, have developed a robust model that can predict when a systemic shift is about to occur, based on methods from a branch of mathematics called topological data analysis. Topological data analysis (TDA) involves extracting information from clouds of data points and using the information to classify data, recognize patterns or predict trends, for example.

Big Data Accelerates Biodiversity Research
Carnegie Mellon University Museums hold the storehouse of specimens required to understand biodiversity across the planet. These archives serve as historical snapshots of biodiversity in one area, at one time. While this information has historically remained isolated, recent efforts to digitize collections have produced a bridge between these rich troves, combining collections into a larger pool that researchers can tap to tackle deep questions about global biodiversity.
